"GRUB loading" message comes from the bootstrap MBR code (the ~440 bytes in sector 0) of the boot device and is activated whilst shift is detected.
The boot-strap code then loads GRUB's core image which is what we might call the real GRUB code, where the $timeout value has an effect. The only way to prevent bootstrap code from displaying the message is *not* to be holding down Shift when it loads. Since the time difference between that point and core image code checking the Shift key flag is probably in the order of a few millionths of a second its not a viable workaround :) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1401318 Title: GRUB menu doesn't appear after showing "GRUB loading."
